Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, my name is ***** ***** I am going to assist you with this.
The first thing you need to do is to give the genset a good tune up - change the oil and oil filter, install a new air filter, and new spark plugs properly gapped to .025".
Make sure the choke is working and properly adjusted.
If this unit has been sitting for a long time, there is a good chance that the carb is bad.
The reason you are losing power to the coil when you release the start button is because something is telling the genset to shut down. That's how the control board shuts the genset down - it kills power to the fuel pump and ignition system.
The hard starting is either a carb or choke issue.
The shut down may be because the genset is no producing power right away.
Connect a voltmeter to the output of the genset, and start it up. See what the voltage is doing. Does it produce 120V as it is starting up, or does it take a few seconds for voltage to build up?
I am going to opt out of this.
Perhaps another expert will help you.
